Thanks Michael,
There is indeed something missing :
ComponentLookupError: ((
zope.schema._bootstrapfields.Int object at 0x01A83610 ,
zope.publisher.browser.TestRequest instance URL=http://127.0.0.1 ),
InterfaceClass zope.app.form.interfaces.IDisplayWidget , u'')
My problem has nothing to do with containers, since my interface is
not a container. It seems that zope can't find the adapters for the shema
fields, even when
I register them by code. I really don't know what to do from now.
The fact is I use AJAX, so I don't need to register my views, I just
call them from code to use the generated html as a response to a
javascript call that then update my page.
Thanks,
Stéphane
